New taxa and notes on palm and false-leaf katydids (Orthoptera: Tettigoniidae: Sexavaini; Pseudophyllinae) from Brunei Darussalam Running title: Sexavaini and Pseudophyllinae from Brunei
As many as 72 species were documented when sampling was conducted in Kuala Belalong in Brunei Darussalam between 2016 and 2017 but this remains non-exhaustive and orthopteran species are still awaiting discovery. Based on new material collected in 2019, two new species of katydids are described here: Segestes nostosalgos sp. n. and Sathrophylliopsis mentham sp. n. These two discoveries are of particular interest: Segestes nostosalgos sp. n. represents the first record of the tribe Sexavaini in Borneo; Sathrophylliopsis mentham sp. n. is drastically different from congeners by the lack of dense fine long hairs around the body
